The study aimed to identify the effectiveness of the use of virtual labs on Development of laboratory skills among the first grade students to detect the significance of statistical differences between the average performance of students with laboratory skills (use of laboratory tools and devices, procedures and implementation of scientific steps by experiment, Result extraction) The experiments were studied by the virtual lab and the control group, which was studied in the usual way, measured by the observation card at post-measurement. The study was followed by a semi-experimental method using two experimental and control groups. The study sample consisted of (40) female students of the first grade intermediate in Al-Majarada governorate. They were randomly distributed to the experimental groups (20) and the (20) In the usual way. The study tool consisted of a observation card consisting of (54) skills, and a website for a virtual lab was designed to teach the separation of movement and simple forces and machines and the separation of the material and its changes with science. The psychometric characteristics of the study tools of validity and Reliability of applying on exploratory sample from outside the original sample study. The results of the study showed the effectiveness of the use of virtual labs in the development of laboratory skills, where a statistically significant differences at the level of significance (0.05) between the average scores by the cognitive achievement test and the degrees of performance of laboratory skills between experimental and control in the post-application in favor of experimental group, the research recommended the use of virtual laboratories in the teaching of science subjects in the intermediate stage, and training of teachers on labs and virtual laboratory.
